Scientific name: Eucalyptus copulans
Eucalyptus copulans is believed to be an established stabilised hybrid between two Eucalypt species, being intermediate in many characteristics between E. moorei and E. stellulata (Black Sally). However, Eucalyptus copulans is geographically distant from E. moorei and E. stellulata, and has distinct and uniform differences, indicating it is a separate taxon rather than a simple hybrid (NSW NPWS 1999a).
Eucalyptus copulans is capable of hybridising with other eucalypt species (NSW NPWS 1999a, 2000a).
Eucalyptus copulans forms a tree up to 20 m high, often with multiple trunks. The bark is smooth, leaden grey in colour, and sheds in ribbons. The lance-shaped leaves are narrow, 612 cm long, 11.8 cm wide, and dull grey/green. The umbellasters (flower clusters) bear 11 white flowers. The fruit is round and 45 mm long (NSW NPWS 1999a, 2000b).
Eucalyptus copulans was originally known from a single population near Wentworth Falls, NSW, west of the Wentworth Falls Railway Station. This population appears to have been completely destroyed in the years following 1957, and by 1991 the species was presumed to be extinct (Hill & Johnson 1991).
In 1993 one plant was discovered in a culvert near the railway line at Wentworth Falls in the Blue Mountains. This tree was located on land managed by the Rail Services Authority. During a storm in September 1996, this plant was blown over. Of the four trunks, one was taken to Mt Annan Botanic Gardens and one to Mt Tomah Botanic Gardens for observation and assisted regeneration (Errington 1997; NSW NPWS 1999a).
A further plant was found in 1998, beside Jamison Creek, about 2 km from the other known tree. This tree is located on council land (NSW NPWS 1999a).
Some dead trees, found near the 1998 location, have a similar appearance to E. copulans. This indicates that the species may have had a wider distribution in the past (NSW NPWS 1999a).
Eucalyptus copulanswas originally known from about six trees. These trees were never relocated and the species was thought possibly to be extinct. The population may have been destroyed in the years following 1957, possibly due to the large fire that burnt through the area at that time. This area appears to have since been cleared for housing (NSW NPWS 1999a).
Eucalyptus copulanswas rediscovered in 1993, with one tree being found. This tree was blown over in a storm in September 1996, and began resprouting from the root ball shortly after (NSW NPWS 1999a). This plant died in 2000 (Blue Mountains City Council 2004).
In February 1998 another individual tree was found. Searches have failed to locate more trees (NSW NPWS 1999a).
The Mt Annan and Mt Tomah Botanic Gardens are propagating seedlings of Eucalyptus copulans, grown from seed collected from the specimens discovered in 1993 and 1998 (Blue Mountains City Council 2004, 2006). In 2006, three propogated tree were planted in Jamison Creek Reserve (Blue Mountains City Council 2006).
Eucalyptus copulans originally occurred in open woodland on swampy, sandy soil adjacent to Jamison Creek near Wentworth Falls in the Blue Mountains (Hill, cited in Harden 1991; NSW NPWS 1999a). However, the species may not be restricted to this type of habitat (NSW NPWS 2000b).
Eucalyptus copulans is found in shallow to moderately deep (less than 50 cm deep to less than 120 cm deep) well-drained sands and soils. The landscape is comprised of rounded, convex crests and moderate to steep inclined sideslopes on Narrabeen Group sandstone. This landscape is mostly found above 600 m above sea level (NSW NPWS 1999a).
Associated vegetation at the culvert site comprises predominantly Leptospermum sp. and a variety of exotic weeds. The less altered site of the second tree is associated with Blue Mountains Mallee (Eucalyptus stricta), Coral-fern (Gleichenia dicarpa), Spiny-leaved Grevillea (Grevillea acanthifolia), Finger Hakea (Hakea dactyloides), Prickly Tea-tree (Leptospermum juniperinum) and Conesticks (Petrophile pulchella).
Weeds at this site include cotoneaster (Cotoneaster sp.), Monterey Pine (Pinus radiata), rhododendrons (Rhododendron sp.), Blackberry (Rubus sp.) and honeysuckle (NSW NPWS 1999a).
The climate of the area is cool temperate, experiencing frosts in winter. Annual rainfall is approximately 1490 mm (NSW NPWS 1999a).
Eucalyptus copulans flowers in summer and autumn, and mature fruit have been collected in May. The seed capsules appear to have very few seeds per capsule, and the seed does not appear to have a high viability (possibly attributable to self-pollination) (NSW NPWS 1999a).
Surveys for E. copulans can be conducted at any time of year, but identification is difficult and requires specialist confirmation. Searches should include swampy areas and creeklines (NSW NPWS 2000a).
It appears that E. copulans has never been abundant since European occupation, possibly only ever occurring in one small population within a geographically small area (NSW NPWS 1999a). Clearing for urban development appears to have reduced much of the suitable habitat for E. copulans. Redevelopment of the area behind Wentworth Falls shops and the clearing and filling of swampy areas for housing are significant factors in the decline of this species (NSW NPWS 1999a).
Eucalyptus copulans is thought to be vulnerable to fire. Until more knowledge is gained on this species' ability to cope with a fire event, fire should be excluded from known individuals (NSW NPWS 1999a).
The locations discovered in 1993 and 1998 have a high degree of weed invasion (primarily garden escapees and Monterey Pine) (NSW NPWS 1999a).
The low numbers of this species makes its existence very tenuous. Unless a few more individual trees are found, the viability of the population is at severe risk (NSW NPWS 1999a).
Eucalyptus copulans has a tendency to cross-hybridise with other species, and the resulting seedlings may not emerge true to type, endangering the continued integrity of the species (NSW NPWS 1999a).
One of the objectives of the Pitt Park Plan of Management is to investigate the possibility of re-establishing a population of Eucalyptus copulans in the Pitt Park Natural Area, using seedlings from the Mt Annan Botanical Gardens (Blue Mountains City Council 2004). In 2006, three seedlings of Eucalyptus copulans were planted in the Wentworth Falls area (Blue Mountains City Council 2006).
Weed removal at E. copulans locations is being undertaken by bush regeneration contractors to Blue Mountains City Council (NSW NPWS 1999a).
The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
